Add less dependecy

[DimitryDushkin]

I think, it's LESS 2.0. Would be nice to add this dependency to package.json.

I wonder what's the best practice for this? We're actually compiling our less using gulp-less.

Well and gulp-less has proper less dependency. I think it's only my problem, because I tried to use library, but compiled by myself with old less (incuded in webpack less-loader).

I think this issue can be closed.
